## Fields

### CREATOR

    public static final Creator<MediaDescription> CREATOR

## Public methods

### describeContents

    public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `writeToParcel(android.os.Parcel, int)`, the return value of this method must include the `CONTENTS_FILE_DESCRIPTOR` bit.

Returns
`int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

### equals

    public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

Parameters
`o` | `Object`: the reference object with which to compare.

Returns
`boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### getDescription

    public CharSequence getDescription ()

Returns a description suitable for display or null.

Returns
`CharSequence` | A description or null.

### getExtras

    public Bundle getExtras ()

Returns any extras that were added to the description.

Returns
`Bundle` | A bundle of extras or null.

### getIconBitmap

    public Bitmap getIconBitmap ()

Returns a bitmap icon suitable for display or null.

Returns
`Bitmap` | An icon or null.

### getIconUri

    public Uri getIconUri ()

Returns a Uri for an icon suitable for display or null.

Returns
`Uri` | An icon uri or null.

### getMediaId

    public String getMediaId ()

Returns the media id or null. See `MediaMetadata#METADATA_KEY_MEDIA_ID`.

Returns
`String` |

### getMediaUri

    public Uri getMediaUri ()

Returns a Uri representing this content or null.

Returns
`Uri` | A media Uri or null.

### getSubtitle

    public CharSequence getSubtitle ()

Returns a subtitle suitable for display or null.

Returns
`CharSequence` | A subtitle or null.

### getTitle

    public CharSequence getTitle ()

Returns a title suitable for display or null.

Returns
`CharSequence` | A title or null.

### toString

    public String toString ()

Returns a string representation of the object. In general, the `toString` method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The `toString` method for class `Object` returns a string consisting of the name of the class of which the object is an instance, the at-sign character ``@`', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

>      getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String` | a string representation of the object.

### writeToParcel

    public void writeToParcel (Parcel dest,
                    int flags)

Flatten this object in to a Parcel.

Parameters
`dest` | `Parcel`: The Parcel in which the object should be written.
`flags` | `int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
